[QUOTE="Solemony, post: 4545891, member: 490361"] [h2]Homework Statement [/h2] Two objects collide on a horizontal frictionless surface. Object 1 comes from the left with mass .753kg and initial velocity of -.28m/s collides with object 2 moving from the right with an unknown mass and an initial velocity of .28m/s. They stick together when collided and moved to the right. The final velocity of object 1 is .2121m/s and velocity of object 2 is .292m/s. Find mass of object 2. [h2]Homework Equations[/h2] M[SUB]1[/SUB]V[SUB]01[/SUB]+M[SUB]1[/SUB]V[SUB]02[/SUB]=M[SUB]1[/SUB]V[SUB]f1[/SUB]+M[SUB]2[/SUB]V[SUB]f2[/SUB] M[SUB]1[/SUB](V[SUB]f1[/SUB]-V[SUB]01[/SUB])/V[SUB]02[/SUB]-V[SUB]f2[/SUB]=M[SUB]2[/SUB] [h2]The Attempt at a Solution[/h2] I have attempted this and got an answer of 30.879 as the mass but the correct answer was .648kg. I'm not sure which step I'm doing wrong because I have gone over several times and see if it was just algebra mistake but it wasn't and still got a really big number. Could someone give some pointers what I'm doing wrong? [/QUOTE]
